摘　　要：介绍了柴油机排气压力的测量方法,计算分析了气波增压器进气即柴油机排出的高压燃气的压力波动对增压器转子流场的影响。探讨了高压燃气平均压力和脉劝度与高压燃气进入转子的深度及扫气角度之间的关系,经回归分析得出三者间的相关方程。推导了平均压力和脉劝度的允许范围,为最大限度地利用高压燃气的能量指明了途径。A method is proposed to measure and record the pressure of diesel exhaust gas (COMPREX intake gas), the effect of the pressure fluctuation on rotator flow field is calculated and analysed. The results show that gas mean pressure and its pulsing degree have an effect on the scavenging angle and gas inflow depth in COMPREX rotator, the regression equations and the range of mean pressure and pulsing degree are then derived, thus providing the approach to utilization of the gas energy to maximum degree.
